摘要
根据高精度GPS变形监测的特点,建立了按历元解算监测点变形量的基本数学模型,并分析了影响变形量精度的主要误差来源。通过对试验数据的计算分析,对数学模型的正确性进行了论证。
The mathematical model,adopting the single epoch algorithm for solving the GPS monitor points deformation information, is established according to the charac- teristics of the high precise GPS deformation monitoring, and the main errors effecting the accuracy of deformations are discussed. The validity of the mathematical model is demonstrated with computing and analysing the test data.
